CDS Invenio (formerly CDSware) is a suite of applications that provides the framework and tools for building and managing an autonomous digital library server.
The project complies with the Open Archives Initiative metadata harvesting protocol (OAI-PMH) and uses MARC 21 as its underlying bibliographic standard. Its flexibility and performance make it a comprehensive solution for the management of document repositories of moderate to large size.
CDS Invenio is developed by, maintained by, and used at, the CERN Document Server. At CERN, CDS Invenio manages over 500 collections of data, consisting of over 800,000 bibliographic records, covering preprints, articles, books, journals, photographs, and more. Besides CERN, CDS Invenio is currently installed and in use by over a dozen scientific institutions worldwide.
Main features:
Navigable collection tree
- Documents organised in collections
- Regular and virtual collection trees
- Customizable portalboxes for each collection

reacTIVision is an open source, cross-platform computer vision framework for the fast and robust tracking of fiducial markers in a real-time video stream. reacTIVision project was mainly designed for the rapid development of table-based tangible user interfaces.

Its tracking core is using Ross Bencinas fidtrack library which is basically a newer high-performance implementation of Enrico Costanzas original d-touch concept. This framework was developed by Martin Kaltenbrunner et.al. at the Music Technology Group, IUA, UPF in Barcelona, Spain as part of the reacTable* project, a novel electro-acoustic musical instrument with a tangible user interface.

reacTIVision is a standalone application, which sends OpenSound Control messages via a UDP network socket to any connected client application. It implements the TUIO protocol, which was specially designed for transmitting the state of tangible objects on a table surface. This framework includes a set of free example client projects for various programming languages, which serve as a base for the easy development of tangible-user interface applications.

The reacTIVision application compiles and runs under the follwing operating systems: Win32, MacOS X and Linux. Under Win32 it suports any camera with a proper WDM driver, such as USB, USB2, FireWire and DV cameras. Equally under MacOS X any such camera supported by QuickTime will work in reacTIVision. Under Linux, FireWire cameras are best supported, as well as a few Video4Linux USB cameras.

NEW: Support the reacTIVision project and buy T-Shirts, posters and other merchandise featuring the reacTIVision fiducial symbols in our web-shop! All designs on these products can be recognized and tracked by the actual reacTIVision software.

Application Handling

Before starting the reacTIVision application make sure you have a supported camera connected to your system. The application can and will not work at all without a camera. Under Win32 and MacOS X the application will ask to select and configure the camera upon startup. Under Linux the camera will be selected automatically. Once configured the application will show a video window with the current camera image in black&white.

Pressing T will show the binary tresholded image, pressing the N key will turn the display off, which reduces its CPU usage significantly!

Pressing the S key will return to the original source image. For convenience and debugging porposes hitting the R key saves a raw image frame, while hitting the B key will save an image in the BMP format.

The P pauses the image analysis completely, hitting ESC will quit the application. The F key toggles the diplay of FPS info in the titlebar. In order to produce some more verbose debugging output, hitting the V key will print the currently recognized symbols to the console.

Command Line Options

The reacTIVision application per default sends the TUIO messages to port 3333 on localhost (127.0.0.1)

In order to change these parameters you can invoke the application with the -h [ip-address] and -p [port-no] options.

reacTIVision needs a so called "tree file" in order to function properly. The default "all.trees" is included and loaded automatically. If you want to use you own tree file you can invoke the application with the -t [tree-file] option.

Optionally if you dont want to analyze the complete image - for example in a square or round table setup - the application can mask a part of the video image with a black region, which speeds up the segmentation algorithm. In order to apply this mask You can invoke the application with the -m [square,circle] option.

Applying the -h or -help option will print a usage message to the console.

Calibration and Distortion

Some tables, such as the reacTable are using a convex mirror in order to increase the area visible to the camera at a minimal distance. This mirror as well as a fish-eye lens unfortunately distort the image. reactIVision includes a correction algorithm, which corrects this distortion with the help of a so called "grid file". These grid files can be generated during a prior calibration process.

To calibrate reacTIVision invoke the application with the option: reacTIVision -c 9 -g [grid_file]

In order to use the this calibration invoke the application with: reacTIVision -g [grid_file]

Prima::Application is root of widget objects hierarchy.

Prima::Application class serves as a hierarchy root for all objects with child-owner relationship. All toolkit objects, existing with non-null owner property, belong by their top-level parental relationship to Prima::Application object. There can be only one instance of Prima::Application class at a time.

SYNOPSIS

use Prima;
use Prima::Application;
or
use Prima qw(Application);

Prima::MainWindow-> create();

run Prima;

USAGE

Prima::Application class, and its only instance are treated specially throughout the toolkit. The object instance is contained in

$::application

scalar, defined in Prima.pm module. The application instance must be created whenever widget and window, or event loop functionality is desired. Usually

use Prima::Application;

code is enough, but $::application can also be assigned explicitly. The use syntax has advantage as more resistant to eventual changes in the toolkit design. It can also be used in conjunction with custom parameters hash, alike the general create() syntax:

use Prima::Application name => Test application, icon => $icon;

In addition to this functionality Prima::Application is also a wrapper to a set of system functions, not directly related to object classes. This functionality is generally explained in "API".
